 //! Provides [`Merge`][], a trait for objects that can be merged.

-//! # Usage

 //! ```
 //! trait Merge {
 //!     fn merge(&mut self, other: Self);
 //! }
 //! ```
 //!
+//! # Usage
+//!
 //! The [`Merge`][] trait can be used to merge two objects of the same type into one.  The intended
 //! use case is merging configuration from different sources, for example environment variables,
 //! multiple configuration files and command-line arguments, see the [`args.rs`][] example.
